Abstract

A SPEED RESPONSIVE COUPLING DEVICE FOR LOCKING A FIRST MEMBER (1) WITH RESPECT TO A SECOND (1) AGAINST RELATIVE ROTATION IN AT LEAST ONE DIRECTION, WHICH DEVICE COMPRISES A RATCHET WHEEL (3) CARRIED BY SAID FIRST MEMBER (1) WHICH IS ENGAGEABLE BY A PAWL (20) CARRIED BY THE SECOND MEMBER (7), AND IN WHICH THE PAWL (20) IS ARRANGED AS A MECHANICAL TOGGLE SWITCH WHICH IS BIASED TO FLIP BETWEEN A "FREE" CONDITION IN WHICH SUCH RELATIVE ROTATION IS PERMITTED AND A "LOCK" CONDITION IN WHICH THE PAWL (20) ENGAGES TO RATCHET WHEEL TO DISALLOW SUCH RELATIVE ROTATION, SAID PAWL (20) BEING LINKED TO A ROCKER (32) WHICH IS SO SHAPED AND DISPOSED THAT WHEN THE PAWL (20) THE PAWL IS IN THE FREE CONDITION, SUCH RELATIVE ROTATION CAUSES THE ROCKER (32) TO ROCK AND THAT WHEN THE SPEED OF SUCH RELATIVE ROTATION EXCEEDS A THRESHOLD VALUE, THE STRENGTH OF THE ROCKING MOTION IMPARTED CAUSES THE ROCKER (32) TO FLIP THE PAWL (20) TO THE LOCK CONDITION.FIG. 1
